------解决方案--------------------
要补充完成这些功能么?
// fill the staff array with three Employee objects
// raise everyone 's salary by 5%
// print out information about all Employee objects

------解决方案--------------------
你要干嘛 把这个类实现吗
------解决方案--------------------
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class EmployeeTest {
  public static void main(String[] args) {

    // fill the staff array with three Employee objects
    Employee[] emp = new Employee[3];
    emp[0] = new Employee( "Tom ", 1000.00, 1970, 4, 1);
    emp[1] = new Employee( "Jerry ", 1200.00, 1971, 5, 2);
    emp[2] = new Employee( "Kate ", 1300.00, 1972, 12, 3);

    // raise everyone 's salary by 5%
    for (int i = 0; i < emp.length; i++) {
      emp[i].raiseSalary(0.05);
    }

    // print out information about all Employee objects
    SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd ");
    for (int i = 0; i < emp.length; i++) {      
      String date = sdf.format(emp[i].getHireDay()).toString();      
      System.out.println( "============================== ");
      System.out.printf( " Employee Name: %s%n ", emp[i].getName());
      System.out.printf( "Employee Salary: %7.2f%n ", emp[i].getSalary());
      System.out.printf( " Hire Date: %s%n ", date);
    }
  }
}

class Employee {

  private String name;
  private double salary;
  private Date hireDay;

  public Employee(String n, double s, int year, int month, int day) {
    this.name = n;
    this.salary = s;
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.YEAR, year);
    cal.set(Calendar.MONDAY, month - 1);
    cal.set(Calendar.DATE, day);
    this.hireDay = cal.getTime();
  }

  public String getName() {
    return this.name;
  }

  public double getSalary() {
    return this.salary;
  }

  public Date getHireDay() {
    return this.hireDay;
